I did more digging and:

1. Starlink bandwidth is better than I was expecting.
2. I can't find the video that did all the math, but basically by using a low Earth orbit network you can get information long distances faster than you can with cell towers and fiber because you're significantly reducing the number of repeaters you need without significantly increasing the distance the information has to travel.
   "Traditional" satellite internet uses satellites that are much higher up, which is where the high latency comes from. The LEO means comparatively lower latency, though the advantage over ground-based networks only works over significant distances. It also means you need more satellites to make a functional network and you need to replace them more often.
   The higher cost to orbit made the old model the correct way to do satellite internet, and now a bunch of billionaires are betting they can replace satellites cheaply enough to make money off a LEO network. Rural customers might be a happy accidental revenue stream, but the most enthusiastic customers will be people sending market information between servers on opposite sides of the globe. To them, billions of dollars can be made by getting information a millisecond before everyone else, so they're the ones who have the biggest interest in using the network.

Umm, high latency means slow reactions. I think you and OP meant the same thing, but you have the terms mixed up
